Least Common Multiple (LCM) for 3 5 3 5 is 15.
LCM(10, 15, 13) = 390.
hcf = 15 lcm = 3510 270 = 2 x 33 x 5 195 = 3 x 5 x 13 hcf = 3 x 5 = 15 lcm = 2 x 33 x 5 x 13 = 3510
hcf(5, 15) = 5 lcm(5, 15) = 15.
The LCM is: 195
The LCM is 15.
The LCM is 585.
The LCM is 15.
The LCM is: 390
13 is prime. The LCM will therefore have to be the product of these two numbers.
